An improved method for processing of nickel bearing saprolite and limonite ores to recover the valuable minerals contained therein, comprising leaching the ore with nitric acid to form a slurry; separating the iron values by precipitation, removing the iron values; forming a liquid/solid residue in which nickel, cobalt and magnesium are in solution, and manganese and aluminum are solid residues inoxide form; conducting a liquid-solid separation and removing the solids; and recovering the nickel, cobalt, and manganese from the liquid-metal concentrate. The leachate is recovered and nitric acidfrom the leachate is recycled.
Description
Invention field
The present invention relates to be used to process metallic ore,, and relate more specifically to be used for reclaiming the method for iron, nickel, cobalt, magnesium, aluminium, chromium and other valuable component of saprolite and limonite ore especially for the method that reclaims nickel and other metal.
Background of invention
Even when when identical mining place is obtained, the composition of ore is also greatly different.Limonite and saprolitic ores contain iron, nickel, cobalt, magnesium, manganese, chromium and/or aluminium usually.The known normally expensive method of method that is used to handle high magnesium saprolitic ores or high ferro limonite type ore, and the present invention is the ore that can handle four corner, comprises the improved cost effective ways of transition ore (transitional ore).As used in this article, term " ore " is intended to represent oxide compound and sulfide ore, metallurgical waste and metallic material, and being interpreted as metal can combine with other element.
Summary of the invention
The present invention is used to process nickeliferous saprolite and limonite ore to reclaim the method for wherein contained valuable mineral.Present method acts on any oxide compound or sulfide ore, metallurgical waste and metallic material, is interpreted as in such material, and metal can combine with other element.If desired, can be with ore grinding or pulverizing, or can mix with other metallic material.With nitric acid lixiviate ore, come precipitated iron by thermal hydrolysis or pH balance then.Randomly, retrieve to reclaim aluminium by reclaiming precipitation or crystallization.Magnesium hydroxide is joined in the solution, thereby make the pH balance to form nickel hydroxide and the cobalt hydroxide that reclaims with precipitated form.
Advantageously, the nitric acid that is used for lixiviate passes through at United States Patent (USP) 6,264, the method of describing in 909 provides, this United States Patent (USP) name is called nitric acid preparation and recirculation (Nitric Acid Production andRecycle), is issued to July 24 calendar year 2001, and is combined in this by reference.
The present invention is particularly useful for reclaiming nickel, cobalt, aluminium, iron, chromium, manganese and magnesium.
Goal of the invention
Main purpose of the present invention provides and reclaim improving one's methods of nickel and cobalt from saprolite and limonite ore.
Another object of the present invention provides the method that reclaims metal values (values) from ore, metallurgical waste and other metallic material.
Another object of the present invention provides preparation nitrate, such as the method for ammonium nitrate, SODIUMNITRATE, saltpetre, nitrocalcite or magnesium nitrate.
The accompanying drawing summary
By following detailed description of reference and back accompanying drawing, aforementioned and other purpose will become more apparent, in the accompanying drawings:
Fig. 1 is the indicative flowchart that the inventive method is represented with its basic form.
Describe in detail
Referring now to accompanying drawing, Fig. 1 shows the inventive method of basic form.Present method is from the fusing (run) of mine saprolite or limonite ore 10 or other metallic material.
Use HNO
3Lixiviate ore adequate time is to form slurries.Although ore can be pulverized, do not necessarily like this, because nitric acid will work effectively, and irrelevant with the size of ore particles.Be lower than 160C, usually about 70C to 130C, but the temperature of preferred about 120C, with nitric acid 20 with about 30 minutes of ore lixiviate 18 ores about 3 hours time extremely.Described acid can be the salpeter solution of 10 to 90% (weight %), but is preferably about 30 to 67% nitric acid, and optimum is about 45 to 55% acid solutions.
The nitric acid 20 that is used for extracting technology is preferably obtained by the nitric acid method for recycling according to United States Patent (USP) 6,264,909 cited above.
Be increased to temperature in about 125 to 200C scopes by heating 22 temperature with extracting solution, preferably to about 165C, with formation liquid/solid resistates, wherein nickel, cobalt and magnesium are in solution, and iron, manganese and aluminium are the solid residues of oxide form.Heating is carried out in obturator, reclaims evolving gas from this obturator and (is mainly NO
x) be used for further processing.Lixiviate and heating steps can carry out in same container, or carry out in isolating container.
PH balance at 22 places by thermal hydrolysis or solution precipitates, and makes iron with Fe
2O
3Form precipitation.
Slurries experience solid-liquid separation, gangue material removes with the solid form.With the heating of remaining liquor, the pH balance by thermal hydrolysis or solution precipitates, and makes iron with Fe
2O
3Form precipitation.
By liquid-solid separation (filtration) with Fe
2O
3Remove with the solid form, thereby stay the solution that contains aluminium, nickel and cobalt valuables.
Aluminium is removed by precipitation at 24 places.Alternatively, aluminium makes and can separate by filtration or by centrifugal with the crystallization of nitrate form.Under any situation, stay nickel-cobalt liquor.
With Mg (OH)
2Mix with nickel-cobalt liquor, its experience pH balance (change) is to form the Ni (OH) of solid form then
2And Co (OH)
2, they are removed (by filtering) with sedimentary form at 26 places.Can also nickel and cobalt valuables be removed from solution by solvent extraction.
Usually through repeatedly evaporating filtrate is concentrated, until remaining Mg (NO
3)
2Be almost anhydrous.Then at 28 places with the magnesium nitrate thermolysis, to form MgO, HNO
3And NO
x, and with nitric acid and nitrogen oxidation recirculation.Resulting MgO can use other place in the methods of the invention.
Employing is at United States Patent (USP) 6,264, and the nitric acid method for recycling of describing in 909 will contain NO at 30 places
xGas form nitric acid again.
By adding or remove nitric acid, or by in solution, adding the change that alkaline-earth metal is finished pH value of solution.
The precipitation of iron is finished at pH 2 to 3 usually;
The precipitation of aluminum oxide is finished at pH 4-5 usually;
The precipitation of nickel is finished at pH 6-7 usually;
The precipitation of manganese is finished at pH 8-9 usually;
The precipitation of MgO is finished at pH 10-11 usually;
The precipitation of Ca is finished at pH 12-13 usually.
Throw out removes by filtration, maybe can be by other currently known methods such as centrifugal the separation.
Any position in entire method under the situation that nitric acid or nitrogen oxide are removed, can be recirculated in the nitric acid recirculation operation with further use.
The achievement of object of the present invention is summed up
